Design characteristicsSoot inertial separation device is set inside boiler and Big volume natural sedimentation chamber is set on the rear arch top&period; Smoke flow speeds is slow here&comma; some particles in the smoke can be separated out because of gravity&period; The smoke turns fast at the head of wing flue&comma; and many particles are separated out because of inertia&period; It lows original emission concentration&period; The ash in the rear arch can fall on the grate by ash falling hole&comma; then be removed&comma; which decreases secondary pollution&period; The boiler operates well and turns out that the original emission concentration is less than 2000mg&sol;Nm³&period; Besides&comma; with the equipped high efficiency dust collector&comma; the boiler emission concentration satisfies national 1-class standard&period;

The intense radiation furnace arch can form reasonable 'A' style fire to prompt the combustion&period; Water cooling wall forms furnace upon the grate&period; It is big enough to burn the coal completely&period; The reasonable arch arrangement ensures flow speed&period; Meanwhile&comma; the inside thread smoke tube&comma; high efficient burning device&comma; well-designed arches and high quality insulation materials and other characteristics ensure the boiler thermal efficiency is higher than national standard&period;

All the circulation are independent and simple&comma; which greatly avoid water cooling wall crack&period;

Performance characteristics

Output

In design perspective&comma; we design bigger contribution allowance&period; Our verifying calculation turns out that the contribution allowance is more than 10&percnt;&period; The boiler operation practice indicates that the use of high efficient heat transfer component----thread smoke tube with enough screw thread makes the boiler output 10&percnt; high than nameplate rated capacity&period;The equipment operates stably&period; The reasonable smoke speed enable no ash deposition on the thread smoke tube in the operation&period; So the boiler output and thermal efficiency won't decrease along with the long operation time&period; As a result&comma; the boiler can keep ideal sustainable output and efficient&period;

Heat efficientThe sufficient heating surface enables the fuel heat be absorbed amply&period; Calculation shows that smoke exhaust temperature is at 160ºC&period; On the other hand&comma; we arrange furnace arch and furnace wall reasonably&period; The furnace wall is tight while the expansion seam is rational&comma; which decrease cool air leak into boiler&period; The boiler thermal efficiency is up to 80&percnt;&period;
